  21.  Prefabrication and ICRA Presentation Outline Sample Interview Questions: Are you familiar with the 2006 ICRA guidelines established by the AIA? Have you used the ICRA guidelines for past or present healthcare projects? Did you have difficulties maintaining any of the procedures outlined in your programs? If so, what were they, and how did you attempt to solve them? Was prefabrication used to any extent during your project? What trades, methods, or specific technologies did you use for prefabrication, and how well did they work? Do you think fabricating materials and systems off site is a viable option to help maintain the ICRA guidelines? Did you have problems with construction interfering with the surrounding occupied spaces? If so, what were they, and how large was the impact?
